Packing



May 9, 1961 J. GLASER PACKING Filed Oct. 21, 1958 7 INVENTOR JULESGLASER Patented May 9, 1961 v 2,933,421 M I J ACK NGQ Jules Glaser,Iluschlikom Switzerland, asslgnor toMax GranicherL-SwitzerlandThe-invention'relates to a packing, constituted, by folding' together-facarton 'blank,'for ho ding a pluralityof articles ofsubstantiallysimilar shape and size in at least one row of compartments formed by twoside panels each connected along a erease'wim a floor portion, and bytransverse-partitions between said sidepanels'i Such packings areintended for holding a plurality of similar articles, such as eggs,fruit, and the like, for transportation and storage, and to protect themfrom damage. For obvious reasons they are therefore required to bestrong, light, and cheap to produce.

Packings of this kind are already known to the art but they still failto give complete satisfaction. Moreover, they have the drawback that thearticles they contain can fall out.

The invention therefore contemplates a packing which will protect thepacked articles, prevent them from falling out, and which can be stackedfor storage without damage being done to their contents. Another objectenvisaged by the invention is to eliminate all waste in production andby cutting down the number of operations required in manufacture toreduce manufacturing cost .to the utmost, apart from facilitating thepacking procedure and thereby minimising the handling costs.

To this end the packing proposed by the invention is provided betweenthe side panels with relatively spaced transverse bridge members eachconnected along a longitudinal crease on each side with a side panel andalong a transverse crease with an upright transverse partition of whichthe sides are connected with the side panels by the formation on eachside between said partition and the side panel of an inwardly foldingflap which is folded during the simultaneous erection of side panels andtransverse partition and doubled back flat against the inside face ofthe side panel, whereupon the floor panels are .folded along theircreases and fixed.

Another advantageous optional feature is that each side panel may form asurface which is broken along a crease extending longitudinally abouthalf way up its side in such manner as to produce an outwardlyprojecting ridge, holding tabs formed by incisions cut into the upperportion, adjoining the bridge member, of each side panel projectinginwards from said creased ridge to engage the rear faces of the flapsformed by the doubled flap part of said portion of the side panel.

An illustrative embodiment of the invention will now be described byreference to the accompanying drawings in which Fig. 1 is a perspectiveview and Fig. '2. is a plan of the blank for producing the packing shownin Fig. 1.

In conventional packings the compartments have a rectangular section.However, if the articles to be packed are of elongate shape, as willapply for instance in the .-case of eggs or pears, then a different forexample pentagonal cross section may be preferred. However,

of the proposed packing,

. when'subjected. to pressure,'for instance when the packings arestacked, the

doubled flap portions side panels would tend to bulge outwards and thedoubled flapsto pull away from the sides. If'steps are taken to preventthis latter efiect, then the packings' will'be unable to bulge. Asuitable embodiment of the invention-which deals with this problem isshown inFigs. land 2. Fig. 1 shows the erected sidepanels 2012.02, the,floor panels 240 which are connected with the side panels along acrease, and the transverse partitions 260 erected between the sidepanels 201, 202', with two, rows of compartments. The drawing also showsthe bridge members 220 spaced at-intervals between the side panels withwhich they are integrally connected along creased folded edges. Thepartitions are again bent down from the bridge members'and their endsare connected with the side panels by the previously described 280, saidflaps being formed between neighbouring bridge members as the cartonblank is erected, in such manner that-when the side panels are foldeddown from the bridge members the flaps fold over inwards and pull 'downthe partitions out of the plane of the bridge members until the flapshave been doubled back completely through 180 and bear against theinside face of the side panels, the floor portions being then folded andfixed in position.

The side panels are broken along a crease 203 extending longitudinallyabout half way up their sides in such manner as to form an outwardlyprojecting ridge on either side. Projecting inwards from this creasedridge 203 in each side panel are holding tabs 204 formed by incisions205 cut into the upper portion of the side panel nearest the bridgemembers 202, said tabs engaging the surfaces of flaps 2.80 which havebeen formed by doubling back part of the same portion of side panel 202.

The two floor panels 240 located on either side of the medianlongitudinal plane of the packing are inclined in an upward directiontowards one another. They are provided with upright lobed portions 241with incisions 242 by means of which they are adapted-to engage thetransverse partitions 260. Moreover, the partitions 260 are themselvesprovided with cooperating incisions 261 for engaging the lobes.

The compartments thus formed have a cross sectional shape which isnearly that of a regular pentagon and they are especially well suitedfor the reception of eggs. To provide resilient support on the floorpanels 240 the latter have U-shaped incisions 2.43 from which U-shapedelastic tabs 244 are formed, their bases being connected with the floorpanels without causing the structure to be weakened.

Occasionally it may be found that the connection between the lobes whichform the longitudinal dividing wall and the transverse partitions is notsufliciently strong for holding heavier articles, such as apples. Whenthe packings are carelessly handled their floors may undo and open.

This difficulty can be overcome if the transverse partitions areprovided with incisions for the reception of the lobes which extendupwards from the floor panels, and which form the longitudinaldivisions, in such manner that these incisions are inclined alternatelyto the right and the left at an angle of at least 5 in relation to thetransverse axis of the partitions. v

If this is done, the lobes which form the longitudinal division willbind in the incisions sufliciently to prevent the floor of the packingfrom becoming undone in any normal conditions.

What I claim is:

1. A carton for holding a plurality of articles of substantially similarshape and size having two rows of containing compartments comprisingside panels forming a surface broken along a crease to produce anoutwardly projecting ridge, floor portions connected to said sidepanels, a longitudinal partition rorm'eiby lobed extensions connected tosaid floor portions, transverse walls between the side panels, bridgemembers connected to said transverse walls and to' said side panels,inwardly folded flaps connected withthe transverse walls and the sidepanels, said flaps being" doubled back flat against the inside face ofthe side panelsand engage'don their rear faces by tongues cut into'theupper part of the side panels along said crease, and engaging the inner,surfaces of said flaps to retain them in position.

2. A carton for holding a plurality of articles of substantially similarshape and size, comprising side panels, a floor portion connected tosaid side panels along a fold, transverse partitions connecting saidsidepanels; transverse bridge members, each connected along longitudinalfolds on either side to a side panel and along a transverse fold with atransverse partition, inwardly folded flaps connecting the sides of thetransverse partition with the side panels, each side panel having alongitudinal fold along the medial portion thereof to form an upper andlower section which define an outwardly projecting ridge, holding tabsstruck from the upper section of each side panel and projecting inwardlyfrom the ing and'beingheldm positionbysaid tabs.

3. The carton of claim 2 wherein the floor portion has lobed extensionswhich are folded upwardly out of the plane of the floor and the ends ofwhich extend in abutting flat contact upwards towards the bridgemembers.

4. The carton of claim 3 wherein the folded lobed portions define slitsfor"cngaging the partitions, said partitions also defining slits forengaging "the: lobes, said first nainedslits being-disposed at 'ananglewith the transverse axis of said partitions.
